Specification of Letters Patent.

Patented May 19, 1908.

Application filed August 17, 1907. Serial No 389,03'i.

To all whom "it may concern:

Be it known that I, SAMUEL .W. BROWN, a citizen of the United States, and a resident of Colorado Springs, in the county of El Paso and State of Colorado, have invented a new and Im roved Chute, of which the following is a ful clear, and exact description.

This invention relates to chutes, and more particularly to chutes for coal or other broken or ranul-ar material.

object 'of the invention is to provide a simple, strong and light chute adapted to be arran ed at an openin in a wall and havin a tilting hopper for directing the matoria l through the opening and serving as a closure for the opening when the hopper is in an 1noperative position.

A further object of the invention is to provide. a chute for-directing broken and granular material such as coal through anopening in a wall, and having a guard for preventing the marring of the wall by the passing material when the chute is in use.

The invention consists in the construction and combination of parts to be'more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming apart of this specification, in which similar characters of reference indicate corresponding parts in all the ,views and in which Figure 1 shows a part of a 'Wall with my chute applied thereto and arranged in a closed osition; Fig. 2 is a section on the line 22o Fig. 1; Fig. 3 is a section on the line 33 of Fig. 1, showing parts broken away; Fig. 4 is a section on the line 4-4 of Fig. 2; Fig. 5 is a section on the line 5-5 of Fig. 2; Fig. 6 is a section on the line 66 of Fig. 1;

and Fig. 7 is a section on the line 77 of.

Tieferring moreparticularly to the parts, 1 represents a part of a wall of a house or ot er building having an opening for the introduction therethrough into the building, of

broken or granular-material such as coal, crushed stone and the like.

ranged in openings of the sides-and held in osition by means of washers 23 and nuts 24. i

he side bolts extend laterally to adjacent supports such as the walls of the building and are rigidly fastened thereto in any suitable' manner. I

The tilting hopper is mounted to swing upon the lower side of the frame 5 and comrises side walls 9 and a bottom 10 formed rom a single piece of sheet metal or other similar material. The bottom 10;)! the tilting hop or forms a closure for the opening in the wall 1 and is strengthened by means of end. and side reinforcing strips 11 and 12 respectively, secured in position by means of rivets 13. Thebottomor closure 10 is further reinforced by means of' transverse strips 14 connecting the side strips. 12 and setween the strips 11 and 14' and the bottom 10 of the tilting hopper are spacing strips 11' and l i 'respectively. -At the upper, inner edge the bottom 10 has a further reinforcing stri 16 secured in position by the rivets 13 an provided with-laterally disposed ends 17. disposed a ainst the side walls 9. -At the inher edges t e latter have reinforcing strips 18 held in positionby means; of rivets. 19 and connected by an integral transverse member 20 extending from side wallto side wall. The end strips 11 and the side stri s 12 extend laterally beyond the edges 'oft e bottom 10, and engage the frame 5 to. limit the inward movement of the hop er. The transverse member 20 engages t einner side of the; frame to limit the outward movement of the tilting be per.

e The em strips 1], and the transverse stri s 14 of the tilting hopper bottom have the'en adjacent to the lower edge of the frame!) cured in place by means of rivets 15. Be

55 rial from the opening into the interior of the,

I provide a casing preferably of sheet metal or similar material adapted to be arranged in theoppning in the wal and comprising sides 2, a top 3 and-a bottom 4. The bottom 4 is arranged at an angle with the horizontal and constitutesan apron for directing the mate-f ing to hinge t e hopper to the casing. The

building. 'A frame 5 of suitable form is arm position.

side walls 9 have a plurality of openings 29. Each of the side wallshas a pivot bolt 30 ar ranged in one of the openings 2?), adjacent to which are located washers 31 having openings to receive the pivot bolt. A guard 32 consisting preferably of a sheet metal plate is mounted upon the pivot bolts 30 by ineans of brackets 33. Nuts 3elare arranged upon the threadedbolts 30 to hold the brackets in A helical spring 35, is carried by each of the .bolts' 30 between the adjacent brackets 33 and the adjacent side wall 9.

-The brackets are secured to the guard by means of rivets 36. The brackets are extended across the apron and reinforce the same. When the hopper is in the inoperative position, closing the opening in the wall, the guard is arranged between the side walls with the edge adjacent to the bottom 10 of the hopper; When the hopper is swung or tilted outward into the operative position, r the guard is swung upward agamst the wall and protects the wall from marring or injury due to the materialpassing rapidly through the'chute. The guard can be swung upward against the wall of the building by hand without di culty, arecess 37 at the edge per mitting the hand of the operator to be inserted underthe edge.

The top of he casing atthe under side carries a; spring latch 38, mounted upon the casing by means of rivets 39, and projecting frame 5. The latch at the projecting end'has outwardly through an opening t0 in the passing over the same and to engage at theshoulder 41 to be held firmly in position thereby. A pad-lock 46 can be arranged in i I the opening 42 of the latch when the hopper is in the inoperative position, to lock the closure 'in position at --the o ening, and thereby to prevent unauthorize entrance to the building throu h the opening in the wall. The end of the soc et 43 op osite the open ing 45 terminates in a hand e 47, by means of whichthe hopper'canbe easily manipulated.

The lower edge of the bottom10 of the ho per extends inwardly beyond the lower si e of. the frame, thereby turning the material from the edge and preventing the gathering 1 of a quantity of the material which won hinder the operation of the ho per. Furthermore, the arrangement'of t e apron 4 and the'bottom 10 is such,-that the angular- 1ty thereof when the chute is in operation assess prevents any of the material from collecting in and choking the chute when the latter is in use. When the hopper is swung into the closed position, the guard will be forced into engagement with the catch or adjacent portions oi the frame, and will thereby be automatically sw ung into position between the sides of the hopper as the latter is closed.

The springs between the brackets 33 and the, 1

side walls of the hopper permit certain resilient .play of the apron when it is oper ated, whereby is avoided any possibility of the jamming or binding of the latter.

As I provide plurality of openings 29 in the side walls 9 or the hopper, it is possible to mount the guard 32- adjustably to make allowance for the form and construction of the wall against which the guard rests when in an operative position. 7

It will be understood that the wall adjacent to the coal chute may be provided with a projecting flange or corn-ice or other pro jection, which would interfere with the guard if the latter were hinged to the side walls at points close to thewall.- By means of the openings 29 however, andthe pivot bolt 30, it is possible to arrange the guard in position so that it will clear the projection of the wall when swung intothe upward position against the same when the hopper is, tilted outward. i
